To all whom it may camera: a Y Be it known that I, J'AoKsoN L. Tnnnnn, a citizen ofthe United States, residing at Stroud, in-the county of Lincoln ,and State of Oklahoma, have invented a new anduseful Cultivator Attachment, of which the .1 01 lowing is aspecification.

The device forming-the subject matter of this application is an attachment for a cultivator of that general i type which-is employed for planting and bedding purposes.

By. its use, a cultivator maybe transformed readily into an implement which will break up'the soil and convert the same intoa loose condition. The attachment'is in-the nature of a fifth plow ,wh'ichwmay be assembled readily with a cultivator ofzanystandard construction.

The invention aims to provide novel means for supporting an auxiliary plow andPfor assembhng the same with a standardculti vator, means being.providedwwhereby the row markings will ber the same distance fromeach other.

- Itis within'th'e scope of the inventionto I improve generally and to enhance the utility of devices of thatrtypeto which the present invention appertains.

With the above and other objects in view which :will appear as the descriptionproceedsthe invention resides in the combination and arrangement of partsand in: the

details of construction hereinafter described and claimed, it being. understood that changes in the precise embodiment of the? invention herein disclosed can be *made "within the scope of what-is claimednwithout departing from the'spirit of the invention;

In the accompanying drawing: Figure 1 shows in vertical longitudinal section, a cultivator of standard construction, to which thepresent invention has been applied; Fig.

2 is a perspective view of the attachment constituting the subject matter. of the present invention; Fig. 3 is a fragmentalhoris zontal section showing certain of the connecting elements; Fig. 4 is a fragmental vertical section of the structure shown in Fig. 3.

i Fig. 5 is a top plan showing the invention applied to a cultivator.

By way of illustration there is shown in the accompanying drawings a cultivator which may be of any desired construction. In the present instance the cultivator is shown as comprising a frame 1 supporting ground wheels 2, the cultivator including rearwardly extended pivotally ported as indicated; ati l for vertical move ment, means 5 being provided Whereby'each bar 3, at the: will of the operator inay be raised-and lowered, as is commonfand well understood by'thoseskilled in the art. The i bars 3carry inner, forwardzstandards 6 and i outer,-rearstandards7, supporting respectively plows G and 74.. Thestandards (Sand 7 are connectedfwithbars 3 for horizontal adjustmentwith respect toeach other, there "1" r 1 by to regulate" the distance between the rows. The foregoing constitutes no part of the present nventionandiis a description of a conventional and wellknown cultivator ;con'-' struction.

- Passing. to a description of the attachment, constituting-the subject. matter of thepres- 'ent invention andreferring particularly to Fig: 2 there "is shown a yoke 8 having rearwardly extended .arms "'10, there being a plurality of, openings '9 formed in the body portion of theyoke 8 and the armslOyhaving openings 11. Links12lieloosely in the openings 11 and Y pivot bolts 1 1' pass through the inner ends ofithe links 12 andare mountl t ed in certain of the openings 9.

At theouterends'offthe links 12 are l'o cated duplicate holding structuresfbut one of which need vbedescribe'dxin detail. 1 Each holding structurecomprises a forward clamp 15 includinga rearwardly extendedstem 16. A rear clamp17 is shown; the same havinga boss lying. fi'n anvopening 19 formed iin the outer end of thelink- 12. The stem 16 of theyforward clamppasses through the rear clamp. and" through xtliefiboss '18. y The rear end-of 'the'stem 16 is surrounded by a Washer 20 engaged by a nut 21. The clamps 15 and. 17 as-shownin Fig. 4 areprovided with gripping knife edges 22. adapted to en Y gage the forward and rear. edges of the inner,

forward standards 6 of the cultivator. Ow-

ing to he. presence of; the bosses 18, the

faces of links'12 under the actionof the nuts 21 and consequently, the links 12 are free, Y a v to swing in a vertical direction upon the rear portions of the stems 16. The openings 11 may be made as large as desired, but, even if the o enings 11 be of comparatively small size, tie outer ends of the links 12 washers 20 do not bind against the rearv will have a considerable movement, owing a tothe fact that the pivot bolts' 14: lie relatively close to the rearwardly extended arms 10. By the construction abovede construction oft he clamps 25 is the same as the clamps 15-l7 shown in Fig. 3, and an extended description is unnecessary. The i" -clamps125 are adapted .to-engage the-outer, i rear standards .7 is upheld. 1 j Theinvention -includes a support '26 .in the =form ofa bar, passing'throughthe-cross arm 1 23 :and through the intermediate portion of ,l the yokerS. Collars 27 surround the-support 26 and are located adjacent the forward; face of the yoke "8 and ithe rear'face of the; cross arm 23,:thecollars being held in place i by set. screws '28. Secured to the rear end of the support 26 is a .fifth .plow 29 which may be ot-zany desired construction.

Recalling that the outer rear plows 7 1 areadapted to be moved toward each other, Y it will be observed that the openings 24 in theeross arm'24 permit such anoperation, it being-possible toimove the sinner forward plows 6 toward each other, owing -to the 1 presence ofthe openings 9, in any 'of which openings, the bolts 14 may be mounted. Thus, by way of-example,athezstructure-may f be adapted for use where :rows are'spaced 1 three feet apart, three feet threeyinches 1' apart, or three .and once half feet apart. The openings 24 permit :the outer rearplows 7 to be moved inwardly withrespect to the inner, forwardplows 6*,1andthe openings 9 permit the inner, forward plows 6 to .be* moved toward each other with respect. tothe iandsthus thecross arm '23 fifth-:plow 29. The rows formed by :the implement, therefore, emay be spaced at equal distances apart. 1

As is zIlIldQIStOOd :readily, Fthe bars '3 may be raised and lowered separately by the re spective raising means'5. ..Noting Fig-2,let I it be supposedthat :the .right hand sidelof the .s'trnetureisto be raised. The centersof swinging movement of ther'bar 23 is the left hand-clamp'25 and the center :of swinging movement o'fthe structure composed'of'the yoke 8 and the-links 9:is theilefthand clamp 15-47,. Now "the'centers of swinging movement represented upon the one hand by the element -25 and upon the other hand by the left hand clamp construction l517 are not coincident and in order to render a raising of the right handside of the structure possible, sufficient flexibility is afforded by the pivot bolts 14. 7

Having thus described the invention, what is claimed is =1. In a device of the class described, a yoke links pivoted to the yoke; clamping means carried by the ends of the links; a cross arm, clamping means located at the ends-of thecross arm; a support mounted in the yoke and in the'cross arm; and a plow carried by the rearend of the support. 2. In a device "of the class described, a yoke tlinkslocated at the ends of the yoke, the links .being connected to the yoke by means of a pin and .multi-hole connection;

clamping means. carried at the ends of'the' links a cross arm; clamps, the clamps being connected withtheends of the cross arm by means of a pin'and :multi-hole connection; a support mounted in the yoke and in the cross arm; and a plow carried by the sup port.

3. In a device of the class described, a yoke including angularly disposed arms having openings; .links'lying in the open- :lngs; pivot elements connecting the links with the body portion of the yoke; standard engaging means carried'at the ends of the links; a, cross arm; standard engaging means-adjustably mounted upon the ends of the cross arm for movement toward-and away .from the ends of the cross arm; a support extended through the yoke and. the cross arm; .movableabutments on thesupport and cooperating,respectively, withthe forward andrear faceof the yoke and the crossarm and aplow mounted on the rear end ofthe: support.
